Mission
AABC establishes industry standards for the field measurement and documentation of HVAC systems and provides education, technical training, and certification for its members. The association’s mission is to identify highly qualified, independent test and balance agencies who are capable of performing work to AABC Standards.
Independence
Independence is the cornerstone of AABC. Members are strictly prohibited from having any affiliations with mechanical contractors, design engineers, or equipment manufacturers. This policy prevents any potential conflicts of interest and ensures that all members provide engineers and building owners with professional, unbiased test and balance services.
Quality Assurance Program
The Quality Assurance Program is an important tool for AABC to monitor the performance of its members, and to quickly resolve disputes or, most often, miscommunications. Click here for more information.

Organization and History
As the complexity of HVAC systems began to increase in the 1960s, a small group of engineers founded the Associated Air Balance Council (AABC) as a non-profit association in 1965. Early on, they recognized the need for independence and stringent membership requirements to ensure objectivity, integrity, and technical expertise, and they made these the guiding principles of the association. AABC also developed the first comprehensive industry standards for test and balance.
